Bottle closure



Patented June 11, 1935 UNIED STATES PA i i BOTTLE CLosUnE Claims.

The present invention relates to closures for bottles of highly carbonated liquids, such as champagne and the like.

' I'he corking of beverages such as champagne 5 in bottles presents considerable difficulty owing to the high pressures exerted by the gases from such beverages. For instance, the gas pressure from champagne may be as much as fifty pounds or more even when the beverage is cool, and at room temperatures the pressure may exceed eighty pounds. The methods heretofore in use have required expensive machinery, and consisted mainly in wedge-shaped corks which had to be compressed in order to insert them in the bottles.

The present invention presents a simple method for securely capping such bottles at a much lower cost.

The invention is illustrated in the drawing, in Which,-

Fig. l illustrates a broken elevation through the neck of a closed bottle, Fig. 2 is a broken view partly in section correspo-nding to Fig. 1, rand Fig. 3 is a detailed view of the binding strip. 25 In carrying out the invention, the bottle I is filled with the liquid, and carbonation is preferably carried out in the bottle by the addition of the proper quantity of solid carbon dioxide. An ordinary cork 2 is then quickly placed in the neck of the bottle with its upper side substantially flush with the opening of the bottle and is covered with a seal, which is preferably a relatively thin layer of resilient material, such as a cork disk 3, of the type customarily used in flanged disk bottle caps. The seal is preferably of substantially the same size as the neck of the bottle and acts as a seal for the cork 2. A narrow binding strip of metal d is then placed over the disk or seal 3, with its edges extending downwardly about the neck of the bottle. Means for securing the ends of the metal strip or tape 4 are pro-vided, for example a wire 5 which is twisted about the ends of the strip. The ends 'i of the strip 5 are then bent back over the wire. The wire V5 is held in position by the annular shoulder 9 on the neck l0 of the bottle i.

The metal strip is of a material which has sufficient rigidity to maintain itself .in its position against the pressure in the bottle. A plurality of strips may be used if desired.

Instead of the wire 5 other anchoring means may be used, as for example a spot-welded ring, or even stiff paper could be wound around the tapes and pasted together. It is preferred to place an ordinary crown bottle cap 6 over the assembly heretofore described, and to secure this cap about the bead 8 in the neck of the bottle in the ordinary fashion.

The cork 2 and the seal 3 may .be of one piece of material if desired, but corks so fashioned are more expensive, and the present form is preferred for this reason, and also because the cork and the seal may in this manner be made o-f different materials, or of materials of different properties.

the prior art.

What I claim as new and desire to secure by Letters Patent is:

1. A package comprising a bead-necked bottle of highly carbonated liquid, a cork in the neck of the bottle, a relatively thin resilient sealing disk overlying the upper end of the cork, a binding strip over said sealing-disk, the edges of said binding strip extending downwardly over the neck of said bottle, means for securing said strip, and a cap fastened about the bead on the neck of said bottle.

2. A package as set forth in claim 1, in which said seal is a cork disk covering the neck of said bottle.

3. A package as set forth in claim 1, in which said binding strip is secured by a wire twisted about the ends of said strip over which the ends of said strip are reversed.

4. A closure for a bottle of highly carbonated liquid comprising a cork in the neck of the bottle, the top of the cork being substantially flush with the opening of the bottle, a seal of resilient material covering the cork and the neck of the bottle, a binding strip over the sealing disk and having its ends extending downwardly over the bottle neck, means for securing the ends of the strip, and a cap overthe assembly and secured about a bead on the neck of said bottle.

5. A closure as set forth in claim 4, in which the binding strip is secured by a ring fastened about the end of said strip, and in which said ring is held in position by an annular shoulder on said bottle.
